well my brother is wanting to do a wall in his truck with a couple of his 15" kicker L7's and used that website to do his design. but i've heard alot of guys on here say that there port tuning is off on that site. I was just curious how off it was? Is it enough to make a big diff?

As far as i could tell with my calculations it was 1.3hz high with anything below 2.5cubes and around 1.7hz high with anything above. But it wont be audible. I use it all the time for guys who just want a system to have some bang with cheap woofers and amps etc.

Ive never had any problems with it, i tuned at 30 hz but it sounded more like 35 for some reason with this calculator vs the box i actually did the math.

the calculator works fine just that it does not account for speaker displacment or bracing if you use it, that's why the frequency that you tune to on the calculator is actually 1-3 hz higher than stated.

Check my sticky at the top of this forum ;)...

With that, I can design a ported enclosure and cut-sheet in less than 5minutes.
